Abstract

A field experiment was conducted during kharif season of 2019 and 2020 in the experimental farm, Department of Agronomy, School of Agricultural Sciences, Nagaland University, Medziphema campus, to study the effect of intercropping of groundnut and soybean with upland rice under different nutrient management practices in the rainfed condition of Nagaland. The experiment was conducted in a randomized block design with three replications. The treatment consisted of five cropping systems C1: Sole rice, C2: Sole groundnut, C3: Sole soybean, C4: Rice + groundnut (3:1), C5: Rice + soybean (3:1) and three nutrient management practices., N1: 100% RDF + FYM @ 2.5 t ha-1 + biofertilizer consortium @ 20 g kg-1 seed, N2: 75% RDF + FYM @ 5 t ha-1 + biofertilizer consortium @ 20 g kg-1 seed, N3: 50% RDF + FYM @ 7.5 t ha-1 + biofertilizer consortium @ 20 g kg-1 seed. Among the different intercropping system, rice + soybean (3:1) recorded the highest nitrogen, phosphorous and potassium (NPK) uptake, grain and straw yield. Among different nutrient management practices, application of 75% RDF + FYM @ 5 t ha-1 + biofertilizer consortium @ 20 g kg-1 seed recorded significantly higher nitrogen, potassium (NPK) content and uptake, grain and straw yield. The results of this experiment indicate that rice intercropped with soybean and application of 75% RDF + FYM @ 5 t ha-1 + biofertilizer consortium @ 20 g kg-1 is superior to other treatments and can be used in similar climatic conditions.

Conclusion

The present investigation revealed that among intercropping systems, rice + soybean intercropping system was found to be most suitable than rice+ groundnut intercropping. This system recorded the highest grain yield. Among the different doses of nutrient management applied, N2-75% RDF along with FYM @ 5 t ha-1and biofertilizer consortium @ 20 g kg-1 seed was found to be most suitable as it registered the highest production under the rainfed condition of Nagaland.
